Dumbledore is more concerned about the eventual fates of the boys who bullied Hermione than he is about the victim. She's smart; she'll survive. That attitude - that smart kids don't need help - is why it's so hard for gifted classes to get adequate funding.

Having Lucius tell Dean how Voldemort would have approved of his actions was brilliant, absolutely brilliant. I'm forced to wonder how many students Minerva forced to be less than they should have been by insisting they "conform"? As for Aunt Cissy, I loved her advice to Hermione.
